This CL changes Checker.genericExprList such that it collects partially instantiated generic functions together with their (partial) type argument (and corresponding) expression lists, instead of trying to infer the missing type arguments in place or to report an error. Special care is being taken to explictly record expression types where needed (because we can't use one of the usual expr evaluators which takes care of that), or to track the correct instance expression for later recording with Checker.arguments. The resulting generic expression list is passed to Checker.arguments which is changed to accept explicit partial type argument (and corresponding) expression lists. The provided type arguments are fed into type inference, matching up with their respective type parameters (which were collected already, before this CL). If type inference is successful, the instantiated functions are recorded as needed. For now, the type argument expression lists are collected and passed along but not yet used. We may use them eventually for better error reporting. Fixes #59958. For #59338.
